Excessive pump cycling in a water pressure booster system is commonly caused by

• A. System leaks
• B. Air in lines
• C. Oversized pump
• D. Low water pressure

Answer: (A)

When a water booster system is pressurized, the pump turns on to raise pressure and then turns off at the set high point. If there’s a leak anywhere in the system, water is lost while the pump is off, causing the pressure to fall back below the low point and forcing the pump to start again. This on-off cycle repeats over and over, leading to excessive cycling. The leak continually undermines the stored pressure, so the pump must repeatedly recharge the system, which wears the pump out and wastes energy. In short, any persistent loss of pressure from leaks is the most common cause of this rapid on-off behavior.
